Yes, gusset is the correct term, but there are a WIDE variety of gussets out there. That style is commonly referred to as a Taco Gusset because of the shape/form.

Kudos to Chris for building a great cage that kept the driver safe. The chassis' are expendable. Glad the driver came through it OK

I'll reiterate (sp?) what Chris said... it is sometimes close to pulling teeth to get guys to upgrade from the minimum. PLEASE stop trying to save money on the cage end. I've had guys request that I NOT put any gussets in because they didn't want to spend the money. How about using those HoHo's for 2 weekends instead of new shoes every race

It's a shame there aren't any pics as they would have taught us something.
